DRAFT-EQUALIZER.

Specification of Letters Patent.

Patented Dec. 11, 1906.

Application filed May 4;, 1906. Serial No. 315.173.

To all whom it may concern:

Be it known that I, AROHIBALD E. WAL- BURN, a citizen of the UnitedStates, residing at Wichita, in the county of Guthrie and State of Iowa,have invented new and useful Improvements in Draft-Equalizers, of whichthe following is a specification.

This invention is a draft-equalizer, and more particularly a device ofthis kind for equalizing the draft of four animals and overcoming sidedraft, the parts being so arranged that the animals can pull abreast.

In the accompanying drawings, Figure 1 is a plan view of the invention,and Fig. 2 is a sectional view on the line 2 2 of Fig. 1.

Referring specifically to the drawings, 5 denotes the main evener-lever,carrying at one end, which is the short end, a. doubletree 6 and at theopposite or long end a swingletree 7. The lever is connected to theshort end of a second lever 8 by a link or strap 9. To the long end ofthe lever 8 are fastened straps 10, which extend above and below thelever 5 and in front of the same and carry a swingletree 11. The link 9is adjustably connected to the lever 5 by a bolt or pin 12, which is eX-tended through one of a series of openings 13 in said lever, the boltserving as a fulcrum for the lever.

Between the stra s 10 and the link 9 the lever 8 has a series ofopenings14 for a bolt or other suitable means, whereby said lever is adjustablyconnected to the tongue or clevis of the plow or other implement, saidbolt also serving as a fulcrum on which the lever swings.

The fulcrum of the lever 5 will be so located that the pull of the twoanimals on the short end against the pull of the one animal on the longend will be equalized. The fulcrum of the lever 8 will also be soadjusted that the pull of the three animals on the short end against thepull of the one animal on the long end will be equalized. All theswingletrees extend in a line in front of the lever 5, so that theanimals can pull abreast.

The device herein described is simple in construction and effectivelyserves the purpose for which it is intended. The fulcrum of the leverscan be readily adjusted so that the animals will pull even and all sidedraft is overcome.

I claim- 1. A draft-equalizer com rising a main evener-lever carrying atits s .ort end a doubletree, and at its long end a swingletree, and asecond lever carrying at its long end a swingletree, and connected atits short end to the main lever.

2. A draft-equalizer comprising a main evener-lever carrying at itsshort end a doubletree, and at its long end a swingletree, a secondlever behind the main lever having at its long end straps which extendin front of the main lever and carrying a swingletree, and a connectionbetween the short end of the second lever and the main lever.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.

ARCHIBALD E. WALBURN.
